LAMP HOLDER SPECIFICATION forming part of Letters AND BRACKET.

Patent No. 273,857, dated. March 13, 1883.

Application filed March 24, 1882. (F model.)

To all whom it may concern:

Be it known that I, WILLIAM KIRK, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented a new and useful Lamp Holder and Bracket, ofwhich the following is a specification.

My invention relates to an improved lamp holder and bracket in which arecombined a device for securing the same to a table, shelf, or to thewall, and extension jointed arms, with a clamping device that firmlysecures the lamp in an upright position and enables me to change theposition of the lamp at will, keeping itin an upright position andpreventing; its being o erturned. I attain these objects by themechanism illustrated by the accompanying drawings, in which- Figure 1is a side view. Fig. 2 is atop view. Fig. 3 is a detailed section ofball-and-socket joint. Fig. at is a detailed top view of the same; Figs.5, 6, and 7, details of the adjustable-clamp.

Similar letters refer to similar out the several views.

A, Figs. 1 and 2, shows the edge of a table or shelf, onto which issecured the arm B by the screw a, forcing the collar 1) up against thetable or shelf A. On the lower end or corner of the arm B, back of thescrew 0, I arrange the pivot-poiutn, cast with thearm B, by which I cansecure the arm B to a side wall by the socket 1, Figs. 1 and 2, that issecured to the wall by ordinary screws, said socket having a recess forthe pivot This allows the arm B to swing to the right or left. To theopposite end of the arm B, I secmc the arm 0, by the bolt 0 and nut d,in such a manner thatit forms a hinge-joint. ()n the opposite end of thearm 0, I arrange for the ball-and-socket joint G. One side of the socketis cast with the arm 0. The other side is a separate piece, as shown byH, Fig. 4.. This cap or side is held in position by the rounded end 1),running back of the proparts throughjection b, and the bolt 9 and thenut g on the opposite end. In this socket is secured the ball cast withthe arm D in one piece. I also connect with the arm D the hinged arm D,hinged at d. ,To control the arm D and D, I

arrange in their center the bolt 73 and nut h, while the springj, woundaround the bolt 6 and abutting against the arms D I), forcesthearmsapart. At the outer end of these arms D and D is cast the segment-shapedclamp F and F. Back of these clamps F and F the arms Paud D are curvedoutwardly, and a groove formed at right angles to the arm, in which Ifit the concaved adjusting-clamps E and E. These clamps are slotted, asshown at Z, Figs. and 6, for the bolts K and K, by which they are heldin connection with the arms D and D and allow of an up-and-dowuadjustment. The con cave faces of the clamp E and the inner faces of theclamps F and F are faced with rubber m m and n n.

In using my invention the holder is secured to the edge of a-table orshelt' by the screw a, the arm B resting on the top of the table andpointingin any direction desired. I then socure the lamp between theconcave clampsE E (if the lamp used hasa standard or colnm n thatconnects it with its base) and close the clamps firmly with the bolt t'and nut h, allowingthe base of the lamp to rest on the table. I thenfasten the ball-and-socket joint G, so that it will hold the clamp in anupright position no matter in what direction I may swing the lamp. Thissocket-jointG, with the ad usting-clamps E and E, enables me to claspthe standard of the lamp at the best place. It the lamp is small, andhas the handle on its-side. I clasp it by the clamps F and F, and if Iwish to use the lamp from the side wall I release the holder from thetable and set the pivot-point into the socket 1. The lamp, in eitherposition, is held securely against overturi'iing.

\Vhat I claim, and desire to secure by Letters Patent, is

1. The arm B, hinged to arm (J, the ball-audsocketjointG. combined withthe hinged clampiug-arms D and D, and the screw '5, nut 11,, andspringj, substantially asdescri bed and shown.

2. The arm B, hinged arm 0, ball-and-socket joint G, with clamp H,hinged arms D D, adjusting-clamps E E, pivot-point a, socket l, screw a,when combined and arranged as specified and shown.
